Invader Zim: Tak, the Hideous New Girl - Ep 20

A new girl at school, Tak, joins the class and "has a crush on Zim" according to the other children. Tak is actually an Irken, and reveals herself after many failed attempts by Zim of trying to get Tak to be his "love-pig" so he can find out more about the humans. Tak reveals her plan to hollow out the Earth's core and fill it with snacks as an offering to the Almighty Tallest. Zim, Dib, Gaz, and GIR team up to try to stop Tak. Zim distracts her in his spaceship while Dib turns off Tak's machine, while GIR and Gaz manage to wreak havoc remotely. At the end, Dib laments that he is unable to explore beyond Earth, only for Tak's abandoned ship to crash right in front of him. This is the third time in the series that Zim saved the human race.
